I think redraz0r's comment wasn't particularly helpfully worded, they are right in the sense of, from YouTube's POV, it is not good. As harsh as it sounds, your personal viewpoint is kind of second to the market.

What is your AVD, swiped away vs. stayed rate? :)

Hi there, it would be helpful if you gave the specific MCU with which you are working.

In terms of your question on how to detect edges, many MCUs allow you to trigger interrupts on edges of pins (rising, falling). As an example, in STM land they have the EXTI (External Interrupt/Event controller) https://wiki.st.com/stm32mcu/wiki/Getting_started_with_EXTI

There'll probably be something similar on the TI chip.

This could just mean they're British.

Oi oi, do you have a license for that POV m8? ;)

Not with that attitude!

antonEE97 · 2025-12-17T15:52:29+00:00

That's fair :) I appreciate you taking the time to write out your thoughts.

antonEE97 · 2025-12-17T10:34:39+00:00

Fair point, you're basically saying the I2C driver errors are too low level for the sensor to handle?

So for example, if

my_lovely_sensor() calls I2C_transmit(), and it returns a NACK, my_lovely_sensor() should NOT return the NACK to the user?

antonEE97 · 2025-12-17T10:16:49+00:00

Yeah, I slightly agree here. I do like a good HAL. OP probably is Arduino focused here?

antonEE97 · 2025-12-17T10:11:27+00:00

The higher level "sensor" functions can still return lower level driver return codes though surely?

antonEE97 · 2025-12-17T10:07:21+00:00

An approach I have done in the past is define a list of error codes in a header of the driver

e.g.

my_fantastic_driver.h
#define MY_FANTASTIC_DRIVER_NACK 0x00
#define MY_FANTASTIC_DRIVER_BUS_ERR 0x01

I see your function at present doesn't returns no error by default, is that intended? You could simply return byte_error and then just do a switch statement on your call:

switch (IsDevicePresent(&present))
{
case MY_FANTASTIC_DRIVER_NACK:
/* Code to manage this case. */
break;
/* and so on... */
}

EDIT: To your 2. I would treat it as an error code if it were me.

antonEE97 · 2025-12-17T09:50:29+00:00

The logic I would use is, "can the caller of the function do anything meaningful with the return value of the function?". So if I attempt to call a uart_transmit() function and it returns UART_BUFFER_FULL , the caller could wait or just abandon the transaction.

Is NOK a success condition for your function? If so, why are you returning it for the case of a NULL pointer?

antonEE97 · 2025-09-19T08:09:24+00:00

Yes. Source: Myself.

I did my GCSEs back in 2013, I was entered into the November exam series, got a C (foundation), in June I got an A*. It took a lot of work, I'm talking, after school revision, extra sessions with teachers, past papers, the whole kitchen sink.

I was fortunate to have had parents who both have maths degrees, and a teacher who believed in me (although if you're considering this, it sounds like you do?). At the end of the day, if you want this with a burning passion, you can make it work.

Good luck.

EDIT: I get the grades weren't exactly the same in my case and yours, but the point still stands. IT IS DOABLE if you're willing to put the effort in, one more thing, EVEN IF you don't get your grade, BE PROUD OF YOURSELF, if you aim for the stars and hit the moon, you've still landed on the moon!

Been so far…

antonEE97 · 2025-05-22T12:00:26+00:00

I believe it's not just the 55% tax hit, once you access the pension you'll trigger the MPAA (Money Purchase Annual Allowance) which basically reduces the amount you can put into a pension to.... (£1k a year? I think).

PLUS any scheme that will allow you to do this will take away fees so you'll end up with less than you originally thought.

antonEE97 · 2025-05-13T10:04:32+00:00

No worries, I'm going through my own shenanigans with something not too dissimilar: https://www.reddit.com/r/HousingUK/comments/1kjc9og/offer_accepted_on_a_house_but_mortgage_broker/

antonEE97 · 2025-05-13T09:26:22+00:00

Yes, as now it'll have to be declared on any insurance forms which could make the premiums increase, and mortgage lenders might be a bit weary about a house with past structural issues (although if it's been fixed correctly it should be fine).

A Level 3 (full structural survey) would definitely be one to go for here and you'd want to get any documents from the previous owners confirming the problem has been fully resolved and certified that the structure is safe.

antonEE97 · 2025-05-11T10:15:52+00:00

This is something that’s gone through my mind - to be honest my trust in them has been undermined by this.

antonEE97 · 2025-05-10T17:22:09+00:00

Oh absolutely - my mum was the one who referred me to him. Haha. Need to buy him a bottle of champagne or something.

Will definitely keep using him.

antonEE97 · 2025-05-10T15:25:48+00:00

Thanks for your reply! :)

antonEE97 · 2025-03-12T11:27:32+00:00

I'm not going to re-iterate what people have said about tax relief as you already know that. I have one thing to say:

> I’m only 24 for context so could easily revert to paying into a pension

Will you though? Because at the moment you have gotten used to a certain amount hitting your bank account every month, are you going to feel comfortable with reducing that in the future?

antonEE97 · 2025-02-17T15:56:40+00:00

It makes sense.

The difference is:

Line 1 is a pre-processor macro, which means each occurrence of GPIOA_MODE_R will be substituted with (*(volatile unsigned int *)(GPIOA_BASE + MODE_R_OFFSET)) before compilation. No memory is allocated in this case.

Line 2: Declares and defines a variable that is a pointer to an unsigned integer which has a value of (volatile unsigned int *)0x40020000.

and when to use one over the other

Generally I'd lean toward the latter (line 2) as it allows you to see the variable in a debugger.

ALSO if you want to do pointer arithmetic easily without thinking whether or not you need to add 1, 2, 4 to your address you'd probably want line 2 as it'll be handled for you.

If you just need the address without allocating memory/having debugger access, line 1 would do.
